Ruskin: Control Damper

Description: The low-leakage insulated control damper features insulated airfoil blades, which offer great strength, produce minimal sound, provide sealing ability, and reduce static pressure loss. It has an 8-inch frame and aluminum construction. When closed, the damper traps a minimum 4 inches of dead air space between the double-blade assembly. Additionally, a thermal break between frame sections prevents heat transmission through the frame, and the blade cavities are filled with urethane foam. The damper’s unique double-edge blade seal design enables higher pressure on either side to assist in blade-to-blade seal shutoff. Seals are mechanically locked in extruded blade slots but can be easily replaced in the field. The TED40x2 also features linkage concealed out of the airstream for low maintenance and reduced air turbulence.

On Demand Refrigerant Safety Classes A2L and A3 have a very low GWP, making them a strong, long-term solution for many HVACR applications. However, these refrigerants are classified as mildly flammable and highly flammable respectively. This flammability class raises safety and compliance concerns. This webinar will help you understand these classes, along with the opportunities these refrigerants can offer.

The webinar is designed to simplify the DOE’s upcoming enforcement of the Annual Walk-In Energy Factor (AWEF) regulation for walk-in coolers or freezers and the impact on refrigeration installations going forward.
